add new membarrier, userfaultfd and switch_endian syscalls

new in linux v4.3 added for aarch64, arm, i386, mips, or1k, powerpc,
x32 and x86_64.

membarrier is a system wide memory barrier, moves most of the
synchronization cost to one side, new in kernel commit
5b25b13ab08f616efd566347d809b4ece54570d1

userfaultfd is useful for qemu and is new in kernel commit
8d2afd96c20316d112e04d935d9e09150e988397

switch_endian is powerpc only for switching endianness, new in commit
529d235a0e190ded1d21ccc80a73e625ebcad09b
